Die Erfindung betrifft ein Common-Rail-Kraftstoffsystem nach dem Oberbegriff des Anspruchs 1. Gegenstand der Erfindung ist ferner ein Verfahren zum Betreiben eines Common-Rail-Kraftstoffsystems nach dem Oberbegriff des nebengeordneten Patentanspruchs.The The invention relates to a common rail fuel system according to the preamble of the claim 1. The invention further relates to a method for Operating a common rail fuel system according to the preamble of the independent patent claim.
Vom Markt her bekannt sind Common-Rail-Kraftstoffsysteme, bei denen der Kraftstoff aus einem Kraftstoffbehälter über eine elektrische Vorförderpumpe zu einer mechanisch angetriebenen Hochdruckpumpe gefördert wird. Diese verdichtet den Kraftstoff auf einen sehr hohen Druck und fördert ihn weiter in einen Kraftstoff-Hochdruckspeicher, der auch als "Common-Rail" bezeichnet wird. An diesen sind mehrere Injektoren angeschlossen, die den Kraftstoff direkt in ihnen zugeordnete Brennräume einspritzen.from Heretofore known are common rail fuel systems in which the fuel from a fuel tank via an electric feed pump is conveyed to a mechanically driven high-pressure pump. This compresses the fuel to a very high pressure and promotes it further into a high-pressure fuel storage, which is also referred to as a "common rail". At this several injectors are connected, which are the fuel inject directly into them assigned combustion chambers.
Die Einspritzvorgänge durch die einzelnen Injektoren sind impulsartig. Durch dieses nur sehr kurzzeitige Abströmen von Kraftstoff aus dem Rail über die Injektoren kann es im Rail zu erheblichen Druckschwankungen beziehungsweise Druckschwingungen kommen. Diese Druckschwingungen setzen sich auch in solche Bereiche des Common-Rail-Kraftstoffsystem fort, die unmittelbar an das Rail angeschlossen sind, beispielsweise bis zu anderen Injektoren. Mit anderen Worten: Die Betätigung eines Injektors führt zu einer Druckschwingung im Rail, die die Zumessgenauigkeit der anderen Injektoren beeinflusst.The Injections through the individual injectors are impulsive. By this only very short-term outflow of fuel from the rail over The injectors can cause significant pressure fluctuations in the rail or pressure vibrations come. Put these pressure oscillations continues into such areas of the common rail fuel system, which are connected directly to the rail, for example until to other injectors. In other words: the operation of a Injector leads to a pressure oscillation in the rail, the metering accuracy of influenced by other injectors.
Aufgabe der vorliegenden Erfindung ist es, ein Common-Rail-Kraftstoffsystem zu schaffen, in dessen Hochdruckbereich, insbesondere in dessen Rail, ein möglichst konstanter Druck herrscht. Dies soll mit einfachen Mitteln und geringem Aufwand realisiert werden können.task The present invention is a common rail fuel system to create in its high-pressure region, in particular in the rail, one possible constant pressure prevails. This should be done with simple means and low Effort can be realized.
Offenbarung der Erfindungepiphany the invention
Die gestellte Aufgabe wird durch ein Common-Rail-Kraftstoffsystem mit den Merkmalen des Anspruchs 1 sowie ein Verfahren zum Betreiben eines Common-Rail-Kraftstoffsystems mit den Merkmalen des nebengeordneten Patentanspruchs 7 gelöst. Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben. Weitere wichtige Merkmale der Erfindung finden sich in der Beschreibung und der Zeichnung. Dabei können die Merkmale alleine oder in ganz unterschiedlichen Kombinationen für die Erfindung wichtig sein, ohne dass an der entsprechenden Stelle darauf hingewiesen wird.The This task is performed by a common-rail fuel system the features of claim 1 and a method of operation a common rail fuel system with the characteristics of the sibling Patent claim 7 solved. Advantageous developments of the invention are specified in the subclaims. Other important features of the invention can be found in the description and the drawing. It can the characteristics alone or in very different combinations for the Invention be important without being in the appropriate place on it is pointed out.
Vorteile der ErfindungAdvantages of invention
Durch die erfindungsgemäß vorgesehene Ventileinrichtung, die mit dem Rail verbunden ist, wird Einfluss auf den dynamischen Druck im Rail genommen, indem das Zuströmen und/oder das Abströmen von Kraftstoff aus dem Rail beeinflusst wird. Die Ventileinrichtung wird zu diesem Zweck derart angesteuert, dass hochfrequente Druckschwingungen des im Rail gespeicherten Kraftstoffs vermindert werden. Dies kann beispielsweise dadurch geschehen, dass während eines Druckbergs ein Abströmen von Kraftstoff aus dem Rail ermöglicht und/oder ein Zuströmen von Kraftstoff zum Rail verringert oder gestoppt wird. Umgekehrt kann bei einem Drucktal ein Zuströmen von Kraftstoff verstärkt zugelassen und/oder ein Abströmen verhindert werden.By the inventively provided valve device, which is connected to the rail, will influence the dynamic Pressure taken in the rail by the inflow and / or outflow of Fuel from the rail is affected. The valve device is controlled for this purpose such that high-frequency pressure oscillations of the fuel stored in the rail can be reduced. This can For example, done by a during a Druckbergs outflow of fuel from the rail allows and / or an influx from fuel to rail is reduced or stopped. Vice versa For example, in the case of a pressure valley, an inflow of fuel can be increased and / or an outflow be prevented.
Damit können hochfrequente Druckschwingungen des im Rail gespeicherten Kraftstoffes, die beispielsweise durch die Betätigung von Injektoren, die an das Rail angeschlossen sind, hervorgerufen werden, verringert und damit der Druckverlauf des im Rail gespeicherten Kraftstoffs geglättet werden. Eine einfache Realisierung besteht beispielsweise darin, die Ventileinrichtung mit der Frequenz der hochfrequenten Schwingungen und gegebenenfalls mit einer Phasenverschiebung gegenüber den hochfrequenten Schwingungen anzusteuern. Die hochfrequenten Schwingungen können dabei entweder von einem Sensor erfasst oder mittels eines geeigneten numerischen Modells berechnet werden. Das Rail selbst und die an das Rail angeschlossenen Komponenten werden auf diese Weise entlastet, was deren Lebensdauer zugute kommt. Für eine gute Dynamik kann die Ventileinrichtung auch mit einem vorgesteuerten Signal angesteuert werden, welches beispielsweise von einer Drehzahl und einem Betriebspunkt der Brennkraftmaschine abhängt.In order to can high-frequency pressure oscillations of the fuel stored in the rail, for example, by the operation caused by injectors connected to the rail, reduced and thus the pressure profile of the stored in the rail Smoothed fuel become. A simple realization is, for example, the Valve device with the frequency of high-frequency vibrations and optionally with a phase shift relative to the to control high-frequency oscillations. The high-frequency vibrations can either detected by a sensor or by means of a suitable numerical model. The rail itself and the on the rail connected components are relieved in this way, what benefits their life. For a good dynamic, the Valve device also controlled by a pilot-controlled signal which, for example, a speed and an operating point of the Internal combustion engine depends.
Dabei kann die erfindungsgemäß vorgesehene Ventileinrichtung arbeiten, ohne eine elektrische Stromversorgung stark zu belasten. Auch die Verlustleistung einer solchen elektrischen Ventileinrichtung ist gering, mit entsprechend geringer Wärmeerzeugung. Die erfindungsgemäße Ventileinrichtung kann darüber hinaus vergleichsweise klein bauen. Kräftige und damit kostenintensive Stelleinrichtung nebst zugehörigen Leistungsendstufen sind nicht erforderlich. Insgesamt wird das Glätten der Druckschwingungen durch die erfindungsgemäß vorgesehene Ventileinrichtung und deren entsprechende Ansteuerung mit geringem Aufwand und geringen Kosten ermöglicht.there can the inventively provided Valve device work without an electrical power supply heavy burden. Also, the power loss of such an electrical Valve device is low, with correspondingly low heat generation. The valve device according to the invention can over it In addition, build comparatively small. Strong and therefore costly Adjusting device and associated Power output stages are not required. Overall, the smoothing of the pressure oscillations by the invention provided Valve device and their corresponding control with low Effort and low cost allows.
Besonders vorteilhaft ist es, wenn die Ventileinrichtung fluidisch in einer Förderleitung zwischen der Kraftstoffpumpe und dem Rail angeordnet ist. Grundsätzlich ist es zwar auch denkbar, eine Ventileinrichtung fluidisch in einer Rücklaufleitung zwischen dem Rail und beispielsweise einem Niederdruckbereich anzuordnen, hierdurch würde der Wirkungsgrad des Common-Rail-Kraftstoffsystems jedoch erheblich verringert. Dieser Effekt wird durch eine Anordnung zwischen Kraftstoffpumpe und Rail vermieden.It is particularly advantageous if the valve device is arranged fluidically in a delivery line between the fuel pump and the rail. In principle, it is also conceivable, a valve device fluidly in a return line between to arrange the rail and, for example, a low pressure area, but this would significantly reduce the efficiency of the common rail fuel system. This effect is avoided by an arrangement between the fuel pump and rail.
Möglich ist auch, dass die Ventileinrichtung in einer Bypassleitung zu einer Förderleitung zwischen Kraftstoffpumpe und Rail angeordnet ist, und dass die Bypassleitung mit einem hydraulischen Speichervolumen verbunden ist. Damit erfolgt die Hauptversorgung des Rails, also die Einstellung des in diesem herrschenden mittleren Kraftstoffdrucks, direkt über die Förderung des Kraftstoffs von der Kraftstoffpumpe über die Förderleitung zum Rail. Der "Wechselanteil" des Kraftstoffdrucks im Rail wird durch das hydraulische Speichervolumen reduziert, welches mittels der Ventileinrichtung abhängig von den hochfrequenten Drckschwingungen mehr oder weniger (bei einem Druckbegrenzungsventil als Ventileinrichtung) oder digital (bei einem Schaltventil als Ventileinrichtung) zugeschaltet wird.Is possible Also, that the valve means in a bypass line to a delivery line between the fuel pump and rail is arranged, and that the bypass line connected to a hydraulic storage volume. This is done the main supply of the rail, so the setting of the in this prevailing mean fuel pressure, directly over the promotion of fuel from the fuel pump over the support line to the rail. The "alternating part" of the fuel pressure in the rail is reduced by the hydraulic storage volume, which by means of the valve device depending on the high-frequency Pressurized vibrations more or less (with a pressure relief valve as a valve device) or digitally (in the case of a switching valve as a valve device) is switched on.
Die Ventileinrichtung kann beispielsweise ein Druckbegrenzungsventil umfassen. Diese wird dann mit einem Signal angesteuert, welches entsprechend den zu dämpfenden Druckschwingungen moduliert ist. Auf diese Weise können auch eher niederfrequente Druckschwingungen vergleichsweise sauber geglättet werden.The Valve device may, for example, a pressure relief valve include. This is then controlled by a signal which according to the to be damped Pressure oscillations is modulated. That way too rather low-frequency pressure oscillations are smoothed comparatively clean.
Eine einfacher bauende Variante umfasst eine Ventileinrichtung mit einem Schaltventil. In diesem Fall wird der von der Kraftstoffpumpe zum Rail geförderte Kraftstoffstrom entsprechend der zu dämpfenden Druckschwingungen "getaktet".A simple design variant comprises a valve device with a Switching valve. In this case, that of the fuel pump to Rail promoted Fuel flow "clocked" according to the pressure oscillations to be damped.
